About this study
Official title: Study of the Features of Senescent T Lymphocytes Induced by Chemotherapy and Its Relationship with the Efficacy of Neoadjuvant Chemotherapy in Young Triple-negative Breast Cancer Patients, a Single-center, Observational Study.
The goal of this observational study is to learn about the features of senescent T lymphocytes induced by chemotherapy and its relationship with the efficacy of neoadjuvant chemotherapy in young triple-negative breast cancer (TNBC) patients.
The main questions it aims to answer are:
Read more
- What are the senescent features of peripheral T lymphocytes in young TNBC patients receiving neoadjuvant chemotherapy and the relationship with the efficacy of neoadjuvant chemotherapy?
- What is the relationship between senescent T cells and adverse events, DFS and tumor infiltrating lymphocytes?
- Participants will receive 6 cycles of docetaxel + adriamycin/epirubicin + cyclophosphamide (TEC/TAC) neoadjuvant chemotherapy, and radical mastectomy after chemotherapy.
2.5ml peripheral venous blood will be collected before chemotherapy, after 2 cycles of chemotherapy, before surgery, and six months after surgery.
3.Clinicopathological data, chemotherapy-related adverse events and prognostic information of patients should be collected during the study.
Read the detailed description
This is a single-center observational study that is expected to enroll 30 breast cancer patients and 10 controls from July 2023 to June 2026. We mainly want to investigated senescent T lymphocytes characteristics during neoadjuvant chemotherapy in young triple-negative breast cancer patients. Besides, the relationship between senescent T lymphocytes and neoadjuvant chemotherapy efficacy also of concern to us.
Inclusion criteria: (1) female, age ≤40 years old; (2) Invasive breast cancer was confirmed by puncture pathology and TNBC (ER-, PR-, HER2-) was confirmed by immunohistochemistry; (3) Patients who meet the indications of neoadjuvant chemotherapy prescribed in the guidelines.
Exclusion criteria: (1) IV patient or history of other malignant tumors; (2) Recently infection or autoimmune disease is not cured or HBV, HIV positive; (3) Had a history of surgery 3 months before enrollment; (4) Patients with insufficient clinicopathological data; (5) Those who do not meet the evidence of neoadjuvant chemotherapy or are unwilling to cooperate.
Withdrawal criteria: (1) the subjects did not receive radical surgery in our hospital or were unwilling to continue to participate in the follow-up study; (2) Termination of chemotherapy due to serious side effects or disease progression during chemotherapy; (3) Research data related to the experiment is missing and cannot be supplemented; (4) Poor specimen quality (hemolysis, contamination, etc.); (5) Follow-up lost.
Participants will receive 6 cycles of TEC/TAC neoadjuvant chemotherapy, and radical mastectomy after chemotherapy. Clinicopathological data, chemotherapy-related adverse events and prognostic information of patients should be collected during the study. 5ml peripheral venous blood will be collected before chemotherapy, after 2 cycles of chemotherapy, before surgery, and six months after surgery. The senescence phenotype of T lymphocytes will be determined by flow cytometry.
The main purpose are:
- Studying the senescent features of peripheral T lymphocytes in young TNBC patients receiving neoadjuvant chemotherapy and the relationship with the efficacy of neoadjuvant chemotherapy.
- Studying the relationship between senescent T cells and adverse events, DFS and tumor infiltrating lymphocytes.
